We compared estimates of inbreeding depression and additive genetic variance for egg-to-adult viability and fecundity obtained from a population of Drosophila melanogaster recently caught from the wild and after being maintained in captivity in the laboratory for about two years. Although estimates of additive genetic variance for viability obtained from response to artificial selection did not change substantially after the period of captivity, inbreeding depression for viability decreased significantly, and that for fecundity increased significantly. The results suggest that inferences on genetic parameters from populations previously maintained in the laboratory should be taken with caution.
